I don't know what to say about Lewis..
He's going to need these 2 weeks to regroup and put in some work in the simulator.
Probably get a haircut too and go play in the simulator 12hrs for 10 days straight.
I noticed Gasly and Doohan got a buzz cut

. It could be to strictly focus on racing and not worry about little things like vanity, or it may well be to do with getting more direct sense of orientation and balance through the helmet.
The G forces will exagerate the weight and vibrations of the head with the helmet as well. And Lewis hair may well dampen some of that direct feel in the corners and under braking.
Just a theory. It wont give him 3 tenths. But the point is he needs to try everything to make progress.
If it's any time for Lewis to drop his side deistractions and fashion stuff it would be now. The microscrope under Ferrari is 10 x worse than at Mercedes.
He will need to take some drastic actions to understand what he needs to do to drive the SF25 as second nature, even if it means throwing it into a wall at high speed in a practice session.
